CHP as a Boiler Replacement Opportunity

The purpose of this paper is to present combined heat and power (CHP) as a viable boiler replacement alternative. To illustrate the potential economic, operational, and environmental benefits of replacing a boiler system with a CHP system, the paper presents a representative analysis that compares a natural gas CHP system to natural gas boilers.

Plant Engineering | When to use electric steam boilers

Sep 06, 2001 · As suggested in Table 1, the fuel cost savings from using a 10 bhp electric boiler, compared to keeping the 150 bhp main boiler in operation, amounts to at least $4.37 per hour in the case of the gas fired boiler. This means that the typical $20,000 installed cost of this electric boiler can be recovered in less than 4600 hours of operation.

CHAPTER 3 COMBUSTION CALCULATION

Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.
